SUMMARY OR ABSTRACT
Text of Note
Understanding the history of Amazonian diversity and how it relates to past environmental changes in the region is fundamental for elucidating processes behind the origin of global diversity distribution patterns and understanding future threats to its preservation. The diversification of Amazonian biota has been a topic of debate for centuries. Recent studies have found that biodiversity in Amazonia is highly underestimated and that many taxa are younger than previously thought. The distribution and dynamics of rivers, vegetation, soil types and moisture gradients created a complex scenario of diversification in the region. These emerging patterns have brought forth new and previously unanswered puzzles regarding the effects of landscape history in Amazonian biodiversity.
